I am using Ubuntu 21.04. Everything was going good, but suddenly yesterday, I couldn't connect to my Wi-Fi. It will connect, but after some time, it will disconnect. When I am very close to the modem there is no problem, but when I am a little far away this issue starts.

I am using Windows alongside Ubuntu. I can use my Wi-Fi with Windows with no problem at a location, but can't use Wi-Fi with Ubuntu at the same location.

Results of sudo journalctl -b 0 -u NetworkManager:

Look at the logs! `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

Thank you, But I don't know the meaning of any of the outputs. I'll paste it here.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
